To all whom z't may concern Be itlrnown that I, 'WILHELM HERMAN man Empire, have invented a certain new and useful Process for Deodorizing ()leic and Fatty Acids Derived from Train or Fish Oils, of whichthe following is a specification.

The oleic and fatty acids obtained from trainor fish-oils by the processes hitherto known could not be used fora great number of purposes onaccount 'of'their strong not be durab y covered by perfumes. Ac,- cording to my present invention, however, it is possible to obtain nearly wholly deodorized oleic andfatty acids from fish-oils.

The products of my new process are preferably intended for manufacturing soaps. The soaps produced with them indeed have a typical smell but it is easy to durably cover manufactured with fatty acids obtained from trainand fish-oils according to theknown processes, in spite of being intensively perfumed, already after a few days show a clear disagreeable and fishy odor.

' The process according to my present invention is performed by applying resins or resinous substances in the following man-. ner: I decompose trainor fish-oils as highly as possible by. means of one of. the

erin and oleic and fatty acids and hereupon ssolved in I a small quantityof oIeiCf'or-J mixed. .with tlie' bulk of fat more easily and, homogeneouslyifj-After this I cause about should not "be allowed .mexcs d- 120 centi grade, as otherwise the reaction would be too violent...

The product thus obtained is black-brown and is distilled in vacuum with" superheated steam before using it. i
